You can probably put the hub in a simple bench mounted vise. Worked for me, and my rotors were, I believe originals, being on there for 22 years and RUST NASTY! I used penetrant of course, and whenever I remove allen head screws, I make sure the allen insert bottoms ALL THE WAY into the head. It's easy to have crud buildup inside, but scraping it out with a little screwdriver pays for itself many times over. After one has removed a few screw heads that need to be welded to, cut, chiseled or ground off, this sort of thing becomes etched into permanent memory. I've learned the hard way.
